[@freebrickproductions]

Helena has/had multiple T-128s? Didn't know that. Shame that the closest one to me now is down in Notasulga.

[@CentralALSirens]

@@freebrickproductions Believe that one met the same fate. Decommission. Hasn't rotated since I believe 2018.

[@CycloneJoey518]

That long wind up tho

[@Supersonic_Sirens_TX]

That wind up doesn't sound right. Great video though!

[@CentralALSirens]

Thanks! Siren is Powered by a VFD (Variable Frequency Drive). So, Single Phase coming in, 3 Phase coming out to the head. So, it's not sounding right at first.

@@CentralALSirens ah ok
